After upgrading from v6.1.26 to v6.1.28, Windows explorer will crash at random. The screen background disappears, the taskbar disappears and after 10~30 seconds it all comes back. The crashes are logged in the Windows event log (example below is the first to occur after booting with v6.1.28) but I have dozens of others if it would help.
This is a new one to me. 6.1.28 has a bug or two, but it affects the host. Can you please try installing 6.1.26 Guest Additions while the host remains on 6.1.28 and see what happens?

I second that, and it probably means that it was an application crash in the Windows user land (not in the kernel). I'd suggest to investigate further as if it happened on a physical PC.
The only possible VirtualBox cause would be Guest Additions Shared Folders, but in that case it's highly unlikely only one person would report the problem.
More likely it is some third party file or disk filter of some kind: e.g. for simulated ISO, remote drive etc.
Upgraded from VirtualBox v6.1.26 -> v6.1.28 but kept my extension pack at v6.1.26:
Failed to open a session for the virtual machine
Implementation of the USB 3.0 controller not found!
Because the USB 3.0 controller state is part of the saved VM state, the VM cannot be started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack' or disable USB 3.0 support in the VM settings (VERR_NOT_FOUND).
Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
Saw this as an interesting MS discussion for this issue: https://answers.microsoft.com/en-us/win ... 06e680b672 then a different post in the other blogs that seem to indicate 7zip as a faulty program in the path. Weird
I just searched for your error (0xc0000005) and it seems it migrated from older Windows version(s), or it got lost in the security files and fixes in new Windows (Explorer has its own zip program built-in). Hope this helps.

Extension Pack version must always match Virtualbox version. Change the EP too.
If you were making this change in response to:

Then please note that Guest Additions != Extension Pack. GAs are inside the VM, EP is on the host.
I must admit I was surprised at the request as I always thought they had to match.
When I upgrade, I upgrade VirtualBox and the extension pack. Once I've booted the guest I install the guest additions (and reboot).
Ah! I see what you're after. You want me to upgrade to v6.1.28 but not run the guest additions as I usually would. Must admit I didn't think that was good form but....

I've upgraded to v6.1.28 again but kept the guest additions at v6.1.26. I have not experienced any Explorer crashes since doing so.
It would appear that the changes to the v6.1.28 guest additions are causing my problem.
Should I continue as I am with this mixed system, or revert to a full v6.1.26?
